Hey the root of the quadratic equation (3x^2)+(6x)_(3) is (√2)-1Hey I derived it myself if it is new than well and enough but if it is old than stillGood .please tell me?

we can pull out a common factor of 3 and it's not gonna change the problem. so now it's x^2 + 2x - 1 = 0

whose roots are +-sqrt(2)-1.

but if you just want sqrt(2) then it's really simple:

x^2 - 2 = 0

done.
